Navigation Display Using Ground Object Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems struggle to help drivers accurately identify upcoming intersections, as the distance-based information is difficult to interpret, leading to potential wrong turns due to the inability to distinguish between similar distances.
Innovation Solution
A method and device that acquire the current position and the position of an intersection, analyze road features to determine a ground object of the intersection, and display this information, allowing for easier identification of the intersection type, such as traffic lights, crossings, or road ends, which are easily recognizable by users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distance-based navigation information is displayed, then drivers can obtain basic navigation guidance, but drivers cannot accurately identify upcoming intersections due to difficulty in interpreting distance information
Solution Approach 1:
The patent transforms the navigation information parameter from abstract distance (meters) to concrete visual landmarks (ground objects such as traffic lights, buildings, trees). This parameter change makes the information directly interpretable by drivers without requiring mental conversion, thereby improving both measurement precision of intersection identification and interpretability of the displayed information.
2Reliability
If simple distance information is displayed, then the navigation system is easy to operate, but drivers cannot distinguish between similar distances leading to wrong turns
Solution Approach 1:
The patent creates visual copies of ground objects (traffic lights, buildings, trees) that will be encountered at the intersection and displays them in the navigation interface. These visual copies serve as proxies for the actual physical objects, allowing drivers to identify intersections by recognizing familiar visual patterns rather than interpreting numerical distance data, thereby improving navigation accuracy while maintaining ease of operation.
3Loss of information
If voice broadcast is used for navigation, then drivers can obtain audio guidance, but drivers cannot hear the navigation voice broadcast clearly in certain situations
Solution Approach 1:
The patent transitions navigation information delivery from the auditory dimension (voice broadcast) to the visual dimension (display of ground object images). This dimensional change allows drivers to receive navigation information through sight rather than sound, overcoming the harmful effect of ambient noise interference while ensuring complete delivery of navigation information.
